<p>PROBLEM TO BE SOLVED: To provide a slope face reinforcement method for constructing a prestress concrete wall extremely excellent in earthquake resistance and rupture resistance on a slope face.SOLUTION: A construction method constructs a prestress concrete wall 52 by being successively arranged along a lower stage from the uppermost stage of the slope face 12, by using a precast concrete plate 11 having an insertion horizontal hole for inserting a PC steel material 47 in the horizontal direction, by inserting a PC steel material 19 into an insertion hole in the vertical direction. The slope face reinforcement method adds compressive force even to the mutual precast concrete plates in the vertical direction, by further tensioning after connecting to the PC steel material of the precast concrete plate of mutual upper-lower stages, by adding the compressive force to the mutual precast concrete plates arranged in parallel by tensioning a laterally fastening PC steel material.</p> |
